Question

(b)) In an isosceles triangle, the base angles are equal. The vertex angle is 40°.
What are the base angles of the triangle? (Remember, the sum of three angles of
a triangle is 180°).​

Answer 1

Answer:

suppose all angle ac A,Band C

If base angle are equal

then A is equal to B

means

40=40degree

then angle C is equal to

40+40+X is equal to 180

180-80=100 degree
